Schloss Katzenberg in Kirchdorf am Inn, Upper Austria, sits upon an ancient Roman road connecting Altheim to Passau, embodying centuries of strategic importance. First mentioned in 1196 as property of the Passau bishops under the name Chotzenperig Castle, it passed to the Counts of Ortenburg in 1251 and subsequently to the influential Mautner family from 1300 to 1525. The original fortress featured a sophisticated defensive design with two encircling moats and a raised fortification wall. Today Katzenberg Castle hosts cultural events, medieval festivals, and Christmas markets, blending its substantial medieval heritage with contemporary community gatherings that draw visitors from across the region.
